### 现象： ###

raise TypeError(“quote\_from\_bytes() expected bytes”)  
TypeError: quote\_from\_bytes() expected bytes

### 原因需要把字符串转成字节 ###

### 解决方案 ###

把

def sign_data(self, data):
            data.pop("sign", None)
            # 排序后的字符串
            unsigned_items = self.ordered_data(data)
            unsigned_string = "&".join("{0}={1}".format(k, v) for k, v in unsigned_items)
            sign = self.sign(unsigned_string.encode("utf-8"))
            # ordered_items = self.ordered_data(data)
            quoted_string = "&".join("{0}={1}".format(k, quote_plus(v)) for k, v in unsigned_items)
            # 获得最终的订单信息字符串
            signed_string = quoted_string + "&sign=" + quote_plus(sign)
            return signed_string

quote\_plus(v)改成quote\_plus(v.encode(‘utf-8’))  
quote\_plus(sign)改成quote\_plus(sign.encode(‘utf-8’))  
quote\_plus函数接收的是字节参数

def sign_data(self, data):
            data.pop("sign", None)
            # 排序后的字符串
            unsigned_items = self.ordered_data(data)
            unsigned_string = "&".join("{0}={1}".format(k, v) for k, v in unsigned_items)
            sign = self.sign(unsigned_string.encode("utf-8"))
            # ordered_items = self.ordered_data(data)
            quoted_string = "&".join("{0}={1}".format(k, quote_plus(v.encode('utf-8'))) for k, v in unsigned_items)
            # 获得最终的订单信息字符串
            signed_string = quoted_string + "&sign=" + quote_plus(sign.encode('utf-8'))
            return signed_string
